    Piston size?

    I bought a cylinder with a bore size of 84.29mm. Does anybody know what size piston kit I should buy.... .25 or .50 oversize?

    I was checking the prox website and they say their .25 over pistons are 84.16mm with my bore of 84.29 that gives a clearance of 0.13mm or .005" do you think that will fly?
